Saving file received via Bluetooth OBEX

[arpit2agrawal]

If I send any file with unknown MIME type (for example abcd.xyz) using File Manager of Nokia E61i via Bluetooth to another Nokia E61i, then abcd.xyz is delivered to Inbox. Now I wish to save this file from Inbox to a specific directory. But when I go to Inbox, it says "Unknown file format".
Basically I want to transfer files with unknown MIME type between phones not by using some software but using built-in file manager. Is this possible?

Thanks in advance
